places where these metals are "subjected tothe constant action of rust caused by -the presence of acids, acidulous waters, alkalis and by the deleterious effects of various atmospheric conditions. It is the object of the presentinventiql to produce a paint of the character above set forth and further, to produce a aint which may be manufactured into soli blocks'for shipment or storage, but is ready for instant use upon being melted by ordinary heat, and may be applied with a brush. Also, it is an. object of this invention to produce it aint which dries to a perfectly smooth, g azed surface, naturally a jet black, without traces of brush-streaks or marring spots, thus permitting its use in places where the most presentable work is desire L,

In the manufacture c has been made of the asphaltio minerals, elaterite and gilsonite, which, when combined by the process hereinafter set forth,

\ have been found to form the basis of a coating which absolutely resists the actions of water, acids and alkali s.

As a first step in the process, a quantity of elaterite, which is known to be insoluble in acids and alkalies, is pulverized, and boiled, under suitable circumstances, with boiled oil in sutlicient quantity to dissolve the elaterite and produce an intimate admixture of the two. then the boiling point is nearly reached, a quantity of resin is added to the mixture. The additionlof resin at this point has been found. to impart an elasticity to the; product unusual in paints, .and. highly ad vantageous. Then, a portion of gilsonite, in" equal quantity as the claterite, is pulverized and boiled with turpentine. Gil sonitc is well-known for its non-conducting properties as well as its resistance to the action of acids and al'kalis, and when combined Specification of Letters Patent. Application filed Kay 29, 1909. Serial n. 499,135.

in suitable quantities with elaterite, pre-" pared as above set forth, forms an unexcelled'limse-for the paint which is the subject of this invention. \Ve have found that the gilsonite usedta one'as a baseis equallyefi'ectivc as whenfcofnbine'd witlrelaterite, the

position as for the double base preparation. We, therefore, do not confine this invention to the limits of the formula usingboth gilsonite and elaterite, but hold the use of both 'or either of the asphaltic minerals tobe wellwitlein .the scope of the invention. f

Sullicient turpentine is boiled with the gilsonite to form a comparatively thin mix-- ture.,,The elateritedissolved in v boiled 0il,.

' is then added to the gilsonite and'turpentine,

the latter mixture beingof such thin consist- .ency' thatthe whole admixture can be properly.worked without the. addition of fur.- ther liquid thinners. It isnecessary that the two minerals be separately boiled and dis -solved,.ow1ng to their different properties and the different times required to properly treat them. a

wearing properties of the product being practically the same for the slngle base com- After the minerals have been poured into the same container or vessel, a quantity of" sulfur is added thereto and allowed to be boiled with the mixture. The sulfur acts to fuse the two asphaltic minerals and cause a perfect con'ibination 'thereof.\ The mix? ture is kept hot beyondtl e point of, fusion, to allow the sulfur to be colnpletely combined or dissolved in the asphal-ltnm, as with the fusion of the parts, its purpose is accomplished, audits further presence in the composition is unnecessary. This last named step, namely the fusion and combined boiling process, has produced -a---1-hen'1ieal change in the mineral products which not entirely clearto us, but,whieh results in a paint having positively, the qualities claimed above for the compound, as 'well as other peculiarities and clarran-teristics not essential to enumerate; To the fused niixture tallow and ozokerite are now added,the,

former to prevent the mass from sticking in composition, and the latter to act as a mineral hardening medium. The mass is then allpwed to root, and prepared for commercial use and the market in any suitable pmzkagc. hut wchave found itdesirableto mold the cooling mass into ln'iq netsor blocks; the composition being well .adapted easily reduced tofiworking condition-by be ing melted over an ordinary heat. The paint is easily applied with a brush and dries-or hardcns with a perfectly smooth, glazed surfu ce,aiidis jet vblack in color. p

" This paint can be made in the open air without being afiected by atmospheric. conditions, and-it is evident that it is Well adapted to beimanufactured on a commercial basis. v t

What Weclaim and desire to secure by Letters Patent of the United States is:

1. A process of making paint,- which coil-f,

sists in dissolving elaterite with boiled oil and gilsonite with turpentine, and combining the minerals by mixing and boiling with sulfur; 4

2. The process of making paint which consists in boilin'ga quantity of gilsonite and turpentine, dissolving an equal quantity of elaterite in boiled oil, adding the two quantitie s, adding a quantity of sulfur and combining the mixture by boiling until the sul fur is combined, and then adding tallow and ozokerite.

' In testimony whereof we alfix our signatures in presence of twowitnesses.
